Encounter a 401 error code while attempting to fetch data from CouchDB using an AJAX request

I attempted to make an AJAX call in a JavaScript file to fetch data from CouchDB.

Unfortunately, I encountered a 401 error message:

Failed to load resource: the server responded with a status of 401 (Unauthorized)

This is an extract of my JavaScript code:

var locate_data = $.ajax({
  url: 'http://admin:mypassword@localhost:5984/database_name',
  type:'GET',
  dataType: "json",
  success: function(data){
    console.log("successfully loaded."), 
    alert(data);
  },
  error: function(xhr) {
       console.log("error"), 
       alert(xhr.statusText)
   }
})

I can successfully retrieve the data from CouchDB using 'curl GET' command in the terminal.

What could be causing this problem? And how do you suggest I resolve it?

To enhance security, you have the option to implement Basic access authentication. This involves including a header field in your requests in the format of 

Authorization: Basic <credentials>
, where credentials are the encoded username and password using Base64, separated by a single colon ':'.

If you're working with Angular, check out this helpful guide on how to apply the same concept (source). While I don't personally use Ajax, it is likely that the implementation would resemble something like this:

$.ajax({
  url: 'http://localhost:5984/database_name',
  type:'GET',      
  headers: {
    'Accept': 'application/json',
    'Content-type': 'application/json',
    'Authorization': 'Basic ' + btoa("<username>:<password>")
  },
  xhrFields: {
      withCredentials: true
  },
  ...
